IMPROVEMENT INVCANISTERS.

Specification forming part of Letters Patent No. 129,842, dated July 23,1872.

SPECIFICATION.

To all'uhom 'it may concern:

Be it known that I, EMMETT MATHER, of Chicago, in the county of Cook andState of Illinois, have invented certain new and useful Improvements inCanisters, of which the following is a full, clear, and exactdescription, which will enable others skilled in the art to whichy myinvention appertains to make and use the same, reference being had tothe accompanying drawing, and in which- Figure 1 represents a canisterprovided with my improvements, a part of the hoop and breast beingbroken away to show the construction of said parts; andFig. 2, avertical central section through the said parts, the same beingenlarged.

My invention consists of a canister having a vertical ange raised aboutthe mouth of the breast, a horizontal flange laid' down inwardly aboutthe inner lower edge of the hoop, which is made in one continuous piece,and these parts united without the use of solder by stamping or settingdown the vertical over the horizontal ange. The hoop of canisters hasheretofore been made of a metallic strip soldered together at the ends,and then either soldered to the raw edge of the mouth of the breast orto a vertical hoop is liable to become detached fromthe breast By makingthe hoop in one continuous piece and laying a ilange about its edge, andby uniting it to the breast by yturning the vertical iiange about themouth of the latter over the ilange of the hoop,7 these objectionablefeatures are not only avoided, but the hoop is more perfect in form, andis stiil'ened so that it retains its shape under ordinary circumstances;besides, the use of solder is dispensed with, thereby cheapening themanufacture of articles of the class referred to.

In the drawing, A represents the canister; B, the breast; and C, thehoop. b represents the vertical iiange l raised about the mouth of thebreast, and ,c the horizontal continuous piece, the latter having ahorizontal flange about its lower inner edge, and united to the zbreast,substantially as shown and described, and for the purposes specified.
